context_page_description: The ceintures de Lyon were a series of fortifications built between 1830 and 1890 around the city of Lyon, France to protect the city from foreign invasion.
  The belts comprised two defensive barriers that included forts, lunettes, ramparts, batteries, and other defensive structures. Many of these structures proved to be ineffective in war due to advancement in weapon technology and the evolution of attack strategies at the time. Some of the fortifications of the ceintures de Lyon have been destroyed, though many remain today.
context_section_description: The second belt, called the Séré de Rivières system, consisted of twenty-six fortifications surrounding the suburban area of Lyon. They were situated in an 8.5 km (5.3 mi) ring around Lyon. The belt was constructed between 1871 and 1890.
